IEELEDGE LINER.

latentcdhltay 17, 1910.

Application filed May 7, 1909, Serial No. 484,535. I Renewed April 4, 1910. Serial lilo. $,2E33.

To all whom, may concern:

citizen of the United States. residing ,at Dedham, in the county of Norfolk and State of Massachusetts, have invented an improve ment in Heel-Edge Liners, of which the folconnection with the accompanying drawings, is a specification,

like figures on the drawings representing like parts.

The invention to be hereinafter described relates to machines for treating the heels of boots and slices. As well known bythose skilled in the art, when the breast of a heel is scoured or treated in the usual' course of manufacture, the edges or corners of the heel extending from the tread surface to the sole of the boot or shoe are left more or less rough or uneven and sometimes with a bur of untrimmed n'iaterial projecting therefrom; and at the point of union or connection between the heel at the base of thesaid edges or corners and thesole of the shoe a pronounced bur or bunch of'untrinnned material is usually present. It has been common to trim or line up the edges .of heels and remove the burs or bunches by means of a knife in the hands ofthe operator, an operation obviously slow, expensive, and unsatisfactoryowing to the non-uniformity of the resulting product. i

With these facts in 'mmd the anus and purposes of the present invention have been to provide means for trimming or lining up the edges or corners of the heel extending from the tread surface to the sole, which shall be economical and rapid in operation, and which will serve to effectually remove any bur or bunch of material along the edges or corners of the heel and at the connection or union of the heel with the sole, all as will hereinafter more fully appear.

In the drawings :-Figure 1 is a side elevation of a suiiicient portion of a shoe treat ing machine to illustrate'the present invention audits associated parts; Fig. 2 is a side View, parts beingin section, showing a shoe, the heel of which is being treated by the heel edge liner; Fig. 3 is a sectional perspective showing the heel liner detached;

and Fig. 4 is a sectional view on line M.

Fig. 1. i

Mountednpon suitable supports 1 is a shaft 2, preferably provided with a driving pulley 3 disposed between suitable shaft V bearings Be 1t known that l, (irnononT; M'oLnon, a source of power by the belt cleaning or polishing brush (3 may be.

secured to the shaft for use as circuin- H stances may dictate, though obviously such brush is not an essential element of the invention.

The shaft 2 is provided with the heel edge liner of the present invention, and said liner may be secured to rotate with the shaft in any usual or desired manncu. In the present embodiment of the invention the end portion of the shaft is preferably screw threaded, as at 7, Fig. 3, and has a collar 8 thereon, the face 9 of which may be countersunk as at 10, to receive the boss 1.1 of a liner support .The liner support 12 may be Va riously formed, but in the present illustrz tion of the invention is of general conical form, having a face 13 disposed in a plane transversely of the shaft 2. A nut 14-. screwthreadcdto the end of the screw-threadedportionilfof the shaft 2, serves to clamp the liner support 12 against the collar .8, as will be readily: understood.

As hereinl'iefore noted, the liner support 12 is preferably provided with a boss or shouldered portion 11, and said bo s or shouldered portion may serve as a (entering element for a disk 15 of abrading material. such as sand paper, emery, or the like, suitable for acting upon the n'iaterial of the heel. In the present invention the disk 15 of sand paper, emery, or the like is made separate from the liner support. 12 and provided with a central aperture, as will be understood, to engage the boss 11, so that when the disk of abrading material 15 is placed upon the 'face13 of the liner support 12, and the latter slid upon the end 7 of the shaft 2 into co-acting relation with the collar 8, the face 9 of said collar 8 and the face 13 of the liner support will serve as a clamp for holding the disk of abrading material 15 firmly in place so as to rotate with the shaft.

Extendingiarounl the periphery of the face 13 of tlic. linersupport 12 isa cutting ring 16, Figs.

16 being formed either as part of the liner support 12 or secured thereto and proecting shghtly. therefrom, as indicated in 3 and 4L, said cutting ring" 'ofthe heel with the sole and at this point,

which requires a different character of treatment, as well understood by those skilled in the art, the cutting ring 16 acts to remove any bur or projection of material.

The cutting ring 16 may be preferably formed of metal and in case the liner support 12 be also formed of metal, the said cutting ring may be formed integral therc with, or if the liner support be formed of other material, the cutting ring 16 may be formed of metal and secured thereto in any usual manner.

In the operation of the device, the'operator takes the shoe in his hand and prescnts an edge or corner of the heel to the action of the liner device, comprising the disk of abrading material 15 and the cutting ring 16, so that from the tread portion of the heel to the point near the connection of the heel to the sole, the .disk of abrading material during its rapid rotation will act upon the corner of the heel to remove any bur or bunch of untrimmed material, and the cutting ring 16 will simultaneously act upon the portion of the heel adjacent the sole or connection to remote the usual bunch or bur at this point.

Of course it will be obvious that various changes in the form or disposition of the parts may be made within-the true scope of the present invention which is definitely set forth by the claims.

lVhat is claimed is:

1. In a heel-edge liner, a shaft, means for rotating the shaft, a disk of abrading material secured to-said shaft to act along the edge or corner of a heel presentedthereto, and a cutting ring closely surrounding said disk of abrading material and forming a peripheral edge thereto to remove any bur or bunch of material at the connection of the heel with the sole.

2. In a heel edge liner, a shaft, means for rotating the shaft, a disk of abrading material secured to said shaft to act along the edge or corner of a'heel presented thereto, and a cutting ring forming a peripheral -material at the connection of the heel with the sole.

1. In a heel edge liner, a shaft, means for rotating said shaft, a liner support having a face extending in a plane transversely of said shaft, a disk of abrading material rotating with said shaft and bearing on the said face of the liner support, and a cutting ring on the liner support surrounding the disk of abrading material to act upon the heel at the connection with the shoe sole.

5. In a heel edge liner, a shaft, means for rotating said shaft, a liner support having a face extending in a plane transversely of said shaft, a clamping collar on said shaft, a disk of abrading material disposed between the clamping collar and face of the liner support to act along the edge or corner of a heel presented thereto, and a cutting ring surrounding said disk of abra'ding material to act upon the edge or corner of the heel at the connection with the sole.

6, In a heel edge liner, a shaft, means for rotating the shaft, a liner support having a cutting face extending in a plane transversely of said shaft, and a cutting ring disposed about the edge of the liner support to act upon the edge or corner of a heel at the connection with the sole of a shoe to remove any bur or bunch at that point.

7. In a device of the character described, the combination of a shaft, means for rotating said shaft, and a heel edge liner rotating with said shaft and having a cutting face for acting along the edges or corners of a heel and a cutting edge having alternate plain and cutting portions to act at the connection of tl. heel. with the sole to remove burs or bunches and line up the heel edges.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
